Compiled Small Stakes stats
 
Hey all,

attached is a preliminary post of the stats from the 2/4 and 3/6 games.

I wanted to do a little more (I also still have to post the correlations), but I also wanted to post this sometime today.. and I'll be running from 9-10 or so, I'll just kinda put this out there now...

There are a few interesting things I'd like to point out... but I'll probably have to wait until tomorrow

This is sort of a rough draft... and I would appreciate anyone's input as to what might make it better.

Big questions:

a) Anything that seems like a typeo?
b) Layout? Is it clear? Im not great with that kinda thing.
c) What do you think of the 0.5 SD range? That was an arbitrary choice. It is flexible...

EDIT: I am interested in keeping this going... so, I will keep the info stored in an splus file on my comp, and would be willing to add to the ball, and update once every 2 months or so.

Re: I hate you tiger woods.... AKA: Stats post
 
Introduction:


The intent of this post is NOT to have players change their game in an effort
to make their stats look more like those presented.

This post is intended to give people who are curious about their stats an idea as
to where other winning players stand. The one-half standard deviation range about
the mean is probably a good range for your stats to be in.

It is very likely that winning players exist whose stats fall outside of many
or all of these ranges. Likewise, it is very likely that some losing players
have stats which fall within all of these ranges.

Stats are great for plugging large leaks. If a player has a VPIP of 8.2% or 34.1%,
they clearly are not playing an optimul number of hands. Examining stats will not
take a 1.5BB/100 winner, and turn him/her into a 2.2BB/100 winner. These improvements
need play time and hand posts.

You might be calling the correct pecentage of river bets, but that doesn't tell us
that you are calling the RIGHT rivers.






Preface:


The two most commonly used statistics when measuring a group of data are: mean
and standard variation.


Mean: This is simply the average. You add all the numbers together, and divide
by the total number of observations.

Standard Deviation: This is the measure of spread. I will leave the complicated
formula out of this. Basically, the further the data tends to fall from the mean, the
greater the standard deviation.

For example:

{5,7,9,11,13} and {1,3,9,15,17}

have the same mean: 9, but the second set has a greater standard deviation.

In addition to these two statistics, the following will also be used:

A one-half standard deviation range about the mean: This is a range that measures

from
0.5 standard deviations below the mean to 0.5 standard deviations above the mean.

For example: In a data set with: mean = 10; standard deviation = 6;

This range is: 7 - 13.


Min: Smallest datum in the set.


Max: Largest datum in the set.





Methodology:


I asked for stat submissions from 2/4 and 3/6 players in the small stakes forum.

I received 21 sets of stats from 2/4 players and 10 from 3/6 players.

(This ended up being roughly 504,000 hands for 2/4 and 313,000 for 3/6).

Using S-Plus software, I proceeded to compute the data in the preface.

this is really cool stuff. I'd participate in any updates.

I steal more, defend my SB less, and win more often when I see the flop than average. I am also looser from the button. interesting stuff...

Well, I'm not surprised to see that I have the highest VPIP and PFR, though someone beats me from the BB.

Thanks this is interesting. I only wish we could corrolate some of these numbers with actual results. Later,

Re: I hate you tiger woods.... AKA: Stats post
 
CallMeIshmael,

Would it be difficult for you to compute baseline SD values for all of the stats you presented? I.E. What is the average SD/100 of a stat like W$SD. Also, what is the standard deviation of the standard deviation of a stat like W$SD. I have always wanted to determine those values for 15/30 full ring and 10/20 6-max, because it would aid PT reads, but I do not have any statistical/database analysis software.

I was thinking about this, and I could make some graphs for the final (as I said, this was only rough).

My concern is that the links may one day be broken. If Im not mistaken, the links in Homer's post on variance are now broken.

Does anyone know of a webspace that isnt going to go down within the near future?

I'm OK with it, either way.

Re: I hate you tiger woods.... AKA: Stats post
 
Could you also take individual stats, like VP$IP and correllate the range of various players and their corresponding win rates? Essentially setting up a curve showing at what VP$IP the highest average win rate is.

This is something I REALLY want to do... but.. it would require two things:

1) A sample size much larger than I have here
2) People to be comfortable giving out their winrate.

To all out there: would you be OK giving me your winrate (again, it is all done anonymously).

Nice work Ishmael!! With any luck this post will contribute to a cutback of the many useless "how do my stats look?" and "what should my stats be?" type posts. The best part of your analysis is the presentation of the data giving both an average stat, the min/max stats, and a SD based range. This is a nice proof positive that not everyone needs to have a VP$IP of exactly 17.635%. Yes it's true - player A can win playing 27% of his hands while player B can be sitting across the table and winning as well playing only 13% of his hands.

Great stuff, and a wonderful reminder that everybody has their own style. While TA-A is a good approach, there's wiggle room for adjustments here and there, and it's nice to see that we don't need to scream at newbies "VPIP>20% IST VERBOTEN!"

Ishmael:

I believe you PMed me about this and I didn't get back to you.

Largely because, well, I don't feel like I have enough hands at either 2/4 or 3/6 to feel remotely confident about my numbers, and I don't think I'm particularly good either.

However, if/when I get more hands, I'll think about sending in some numbers to this project.

Great work and great post. I'd also like to see win rate and win rate correlations. I'm only 1.5BB/100 on $3/$6 over 22,000 hands, but I will send you my stats if you want them (I can't imagine you do).

Optimal is misspelled.

Actually, those stats are fine. It is statistically likely you are not winning by chance.

Interesting analysis. Some histogram plots might further help describe the spread of the data. I'd also be interested in seeing a scatter plot of VPIP vs. W$WSF. If you re-run the analysis, I'd be happy to send you my most recent PT stats.

This is an awesome post Ishmael. It's saved me from posting my stats.


I think this is helpful because it makes you take a look at an area you may not think that you had a problem in. By saying, "my stats are completely different then what I see here" to yourself, it allows you to take a look at some of your play and see if your stats are different for a good reason, or a bad one. Keep up your good work on this.

Thanks a lot.

Re: I hate you tiger woods.... AKA: Stats post
 
This is a great project but there are few issues I have... your sample is tiny -~500K hands.I think players that you got numbers from are probably not allstar players in the limits you are studying so I'm not sure these numbers are something an aspiring player may want to copy..newbies yes this type of information is very helpful just to get a feel for some helpful parameters.I would really like to see the win-rates of the players involved.Obviously the really great players dont hang around they move up..but looking at some of these stats gives me the feeling many of these players are not 2.00 bb/+ players let alone 1.00bb I could go into why I think that but dont have time right now-some of thess stats look kind of funky.What would be great would be if you could get 10-20 50K/100K/200K hand databases from very good players-hard to get it all together thu I know.I have one for $3-6 on one database but alot of my other data which would qualify for your study is mixed in over a dozen old databases
Great work btw this post has been added to my favorites.I'd like to help if I can I'm surprised at all the great threads in this forum...since I've run pretty crappy in $3-6 my last 15K hands....I'm nosing around.

Thanks for the reply.

Couple things...

I feel this can be a common misconception.

Many stats (ie. VPIP, PFR, VPIP from SB, Steal blinds, defend blinds (and many more)) take a binomial distribution. And 500k is far more than enough of a sample size to be quite certain in its accuracy.

For example, if your preflop raise is 10%, after 500k hands, you can be 95% sure that your true rate falls in this range:

9.999-10.00008

Thats pretty accurate!

I went very far out of my way to be able to keep winrates and two plus two identities anonymous in the study.

Many choose to break this, some didnt. So, I have winrates for some.

But... I made sure to state that for your stats to be relevant, you had to be beating the game my more than 1 standard deviation. Thus, these were generally solid players.

[/ QUOTE ] I didnt know that you had screened for "decent players"...did this evolve over the course of time or did you from the start only accept data from decent players?If you intially had taken the larger samples from less than stellar players your stats could be polluted and obviously biased to the stats of these less than great players.Having 400K in stats from 1.00bb/100 players and 100K from 2.00bb+/100 players could hurt your results obviously...not that you intended to create the perfect statistical model here of a very good from the start but it could move towards that if you wanted to keep working on it.

What was the bb/100 you used to screen players?

Sorry if I'm being a dolt I think this is awesome what you are doing here!

I put a message on the board, and basically said: "If you are winning by this much (insert description) and would like to participate... then go here (insert website). If you are not sure, then PM me to talk"

I also sent out PMs to about 100 regular small stakes posters, who seemed to post good advice/hands, and personnally asked if they would like to contribute.

(NOTE: Im sure I missed a TON of people, and skipped some others because I didnt know if they played the right limits. If you didnt get a PM, it doesnt mean anything!!)

I am bumping this because I think it contains a lot of great info and there seem to have been a lot of stat posts lately...
